Where to Find What?

I have confessed on this blog that I have Mr. Monk DVDs for a reason. We like to categorize, tag, painstakingly re-organize, and re-use. This is reflected in our Innovations in Agriculture …

The Seedbank: Left-over squared timber met the chopsaw.

The Nursery: Rebirth of copper tubes and newspapers.

… as well as in my periodical Raking The Virtual Zen Garden: Updating collections of web resources, especially those related to the heat pump system.

Here is a list of lists, sorted by increasing order of compactification:

But thanks to algorithms, we get helpful advice on presentation from social media platforms: Facebook, for example, encouraged me to tag products in the following photo, so here we go:

The Stages of Blogging – an Empirical Study

… with sample size 1.

Last year, at the 4-years anniversary, I presented a quantitative analysis – in line with the editorial policy I had silently established: My blogging had turned from quasi-philosophical ramblings on science, work, and life to no-nonsense number crunching.

But the comment threads on my recent posts exhibit my subconsciousness spilling over. So at this anniversary, I give myself permission to incoherent reminiscences. I have even amended the tagline with this blog’s historical title:

Theory and Practice of Trying to Combine Just Anything.

Anecdotal evidence shows that many people start a blog, or another blog, when they are in a personal or professional transition. I had been there before: My first outburst of online writing on my personal websites predated quitting my corporate job and starting our business. The creative well ran dry, after I had taken the decision and had taken action – in the aftermath of that legendary journey.

I resurrected the old websites and I started this blog when I was in a professional no-man’s-land: Having officially left IT security, still struggling with saying No to project requests, working on our pilot heat pump system in stealth mode, and having enrolled in another degree program in renewable energies.

The pseudonymous phase: Trying out the new platform, not yet adding much About Me information. Playing. In the old times, I had a separate domain with proper name for that (subversiv.at). This WordPress blog was again a new blank sheet of paper, and I took the other sites offline temporarily, to celebrate this moment.

The discovery of a new community: The WordPress community was distinct from all other professional communities and social circles I was part of. It seems that new bloggers always flock together in groups, perhaps WordPress’ algorithms facilitate that. I participated with glee in silly blogging award ceremonies. However, I missed my old communities, and I even joined Facebook to re-unite with some of them. Living in separate worlds, sometimes colliding in unexpected ways, was intriguing.

Echoes of the past: I write about Difficult Things That I Handled In the Past – despite or because I have resolved those issues long before. This makes all my Life / Work / Everything collections a bit negative and gloomy. I blogged about my leaving academia, and my mixed memories of being part of The Corporate World. It is especially the difficult topics that let me play with geeky humor and twisted sarcasm.

The self-referential aspect: Online writing has always been an interesting experiment: Writing about technology and life, but also using technology. As philosophers of the web have pointed out, the internet or the medium in general modifies the message. I play with websites’ structure and layout, and I watch how my online content is impacted by seemingly cosmetic details of presentation.

Series of posts – find our favorite topic: I’ve never participated in blogging challenges, like one article a day. But I can understand that such blogging goals help to keep going. I ran a series on quantum field theory, but of course my expertise was Weird Internet Poetry … yet another demonstration of self-referentiality.

The unexpected positive consequences of weird websites – perhaps called ‘authentic’ today. They are a first class filter. Only people who share your sense of humor with contact you – and sense of humor is the single best criterion to find out if you will work well with somebody.

Writing about other people’s Big Ideas versus your own quaint microcosmos. I have written book reviews, and featured my favorite thinkersideas. I focussed on those fields in physics that are most popular (in popular science). My blog’s views had their all-time-high. But there are thousands of people writing about those Big Things. Whatever you are going to write about, there is one writer who cannot only write better, but who is also more of a subject matter expert, like a scientist working also as a science writer. This is an aspect of my empirical rule about your life being cliché. The remaining uncharted territory was my own small corner of the world.

Skin in the Game versus fence-sitting. Lots of people have opinions on many things on the internet. The preferred publication is a link to an article plus a one-liner of an opinion. Some people might really know something about the things they have opinions on. A minority has Skin in the Game, that is: Will feel the consequences of being wrong, personally and financially. I decided to focus on blogging about topics that fulfill these criteria: I have 1) related education and theoretical knowledge, 2) practical hands-on experience, 3) Skin in the Game. Priorities in reverse order.

The revolutionary experiment: Blogging without the motivational trigger of upcoming change. Now I have lacked the primary blogging impulse for a while. I am contented and combine anything in practice since a while. But I don’t have to explain anything to anybody anymore – including myself. I resorted to playing with data – harping on engineering details. I turn technical questions I get into articles, and I spend a lot of time on ‘curating’: creating list of links and overview pages. I have developed the software for my personal websites from scratch, and turned from creating content to structure for a while.

Leaving your comfort zone: I do edit, re-write, and scrutinize blog postings here relentlessly. I delete more content again than I finally publish, and I – as a text-only Courier New person – spend considerable time on illustrations. This is as much as I want to leave my comfort zone, and it is another ongoing experiment – just as the original stream-of-consciousness writing was.

But perhaps I will write a post like this one now and then.

Same Procedure as Every Autumn: New Data for the Heat Pump System

October – time for updating documentation of the heat pump system again! Consolidated data are available in this PDF document.

In the last season there were no special experiments – like last year’s Ice Storage Challenge or using the wood stove. Winter was rather mild, so we needed only ~16.700kWh for space heating plus hot water heating. In the coldest season so far – 2012/13 – the equivalent energy value was ~19.700kWh. The house is located in Eastern Austria, has been built in the 1920s, and has 185m2 floor space since the last major renovation.

(More cross-cultural info:  I use thousands dots and decimal commas).

The seasonal performance factor was about 4,6 [kWh/kWh] – thus the electrical input energy was about 16.700kWh / 4,6 ~ 3.600kWh.

Note: Hot water heating is included and we use flat radiators requiring a higher water supply temperature than the floor heating loops in the new part of the house.

Heating season 2015/2016: Performance data for the 'ice-storage-/solar-powered' heat pump system

Red: Heating energy ‘produced’ by the heat pump – for space heating and hot water heating. Yellow: Electrical input energy. Green: Performance Factor = Ratio of these energies.

The difference of 16.700kWh – 3.600kWh = 13.100kWh was provided by ambient energy, extracted from our heat source – a combination of underground water/ice tank and an unglazed ribbed pipe solar/air collector.

The solar/air collector has delivered the greater part of the ambient energy, about 10.500kWh:

Heating season 2015/2016: Energy harvested from air by the collector versus heating-energy

Energy needed for heating per day (heat pump output) versus energy from the solar/air collector – the main part of the heat pump’s input energy. Negative collector energies indicate passive cooling periods in summer.

Peak Ice was 7 cubic meters, after one cold spell of weather in January:

Heating season 2015/2016: Temperature of ambient air, water tank (heat source) and volume of water frozen in the tank.

Ice is formed in the water tank when the energy from the collector is not sufficient to power the heat pump alone, when ambient air temperatures are close to 0°C.

Last autumn’s analysis on economics is still valid: Natural gas is three times as cheap as electricity but with a performance factor well above three heating costs with this system are lower than they would be with a gas boiler.

Is there anything that changed gradually during all these years and which does not primarily depend on climate? We reduced energy for hot tap water heating – having tweaked water heating schedule gradually: Water is heated up once per day and as late as possible, to avoid cooling off the hot storage tank during the night.

We have now started the fifth heating season. This marks also the fifth anniversary of the day we switched on the first ‘test’ version 1.0 of the system, one year before version 2.0.

It’s been about seven years since first numerical simulations, four years since I have been asked if I was serious in trading in IT security for heat pumps, and one year since I tweeted:

Self-Sufficiency Poetry

Our self-sufficiency quota for electrical energy is 30%, but what about the garden?

Since I haven’t smart metered every edible wildflower consumed, I resort to Search Term Poetry and random images. This is a summer blog post, lacking the usual number crunching and investigative tech journalism.

(Search terms are from WordPress statistics and Google Tools)

Direct self-consumption quota was nearly 100% last year (no preservation), and self-sufficiency was very low, with one exception: Yarrow tea.

This year we will reach 100% herbal tea self-sufficiency:

Yarrow TeamThe solar/air collector is boosting yarrow harvest – and we have yet to include its cosmic quantum free energy focusing effect in the marketing brochure.

But it also boosts vitality of other life forms:

Slimey Aliens near collector

I cannot prove that these particular slimy aliens – edible and a protected species in Austria – are harmful as I never caught them red-handed. You just need to be careful when collecting vegetables to avoid the slimy parts.

We are self-sufficient re green ‘salad’ and ‘fake spinach’ for about half a year. Our top edible wild flowers in terms of yield are Dandelion, Fireweed, Meadow Goat’s Beard …

Last year exactly one seedling showed up, and we left it untouched. This year the garden was flooded with purple plants in spring:

There are two main categories of edible plants – and two different branches of the food chain: Things we mainly eat, like tomatoes, herbs, onion, and garlic …

Garlic, tomatoes, herbs

… and the ones dedicated to alien species. Top example: The plants that should provide for our self-sufficiency in carbohydrates:

In the background of this image you see the helpful aliens in our garden, the ones that try to make themselves useful in this biosphere:

But looking closer, there is another army of slimy life-forms, well organized and possibly controlled by a superior civilization in another dimension:

This garden is fertilizer- and pest-control-free, so we can only try to complement the food chain with proper – and more likeable – creatures:

Hedgehog, Potatoes

Yes, I have been told already it might not eat this particular variety of aliens as their slime is too bitter. I hope for some mutation!

But we are optimistic: We managed to tune in other life-forms to our philosophy as well and made them care about our energy technology:

This is a young blackbird. Grown up, it will skillfully de-slime and kill aliens, Men-in-Black-style.

Life-forms too quick or too small for our random snapshot photography deserve an honorable mention: Welcome, little snake (again an alien-killer) and thanks mason bees for clogging every hole or tube in the shed!

It is a pity I wasted the jurassic park search term on the snail already as of course we have pet dinosaurs:

So in summary, this biotope really has a gigantic bug, as we nerds say.

Travelling Like Spam Poetry

We have an anniversary.

In the summer of 2005,
the Chief Engineer and I set out to visit every Austrian village
whose names started with the letter Z.

It was a straight-forward idea given that we lived in a z-village. Our universe of websites contains the virtual equivalent – z-village.net, a German website chronicling the adventures and musings of two fearless settlers – calling themselves Subversive Element and Irgendwer (Somebody Doing Anything Nobody Wants to Do). These setters are on a mission to discover myth-enshrouded z-village. Today the z-village website is an epic tomb, but we link to it on our blog: punktwissen – Professional Tinkerers and Restless Settlers, tagging it with How it all got started. Perhaps that’s why not every reader recognizes this blog’s business-y nature.

Now, after I have scared everybody off with weird links (…. wait, I forgot to mention that it was the other members of our EPSI circle that suggested this trip!), here is the story:

We used the official list of z-villages from Austria’s statistical service – 247 places in total in a manual approach to optimization: Trying to visit as many as possible in one round trip. In the end, we managed to see 100 z-villages, driving 2000 km in about 10 days.

So the process was:

Try to find the next z-village shown in your print-out of Google maps or referred to in other sources. Most of these villages were small settlements rather than political entities, comprised of houses with addresses like z-village 7, and finding those was like trying to follow a yellowed old treasure map.

z-tripz-tripFind a place-name sign.

z-trip, found sign.Take a weird photo of the sign (Collection).

z-trip

Take to our heels when local life-forms start wondering. Sometimes it was scary, like Indiana Jones meeting the cannibals. In the north of Austria near the border to Czech Republic  – places typically picked for stereotype dark-family-secret-in-rural-village crime stories – the locals were especially suspicious.

Look, these guys are taking a photo of the sign ????!!!

z-trip, scary place

I realize, it might be hard to see the fun in this. You need to be part of it. Later I proposed this type of travelling to become part of life coaches’ outdoor training offerings. In jest of course, but as usual some people took it seriously.

Via the silly rule implied by the list of names we were forced to travel to places you would never pick for any type of vacation: They were neither advertised to tourists nor intriguing to maverick adventurers. It was like clicking form one hyperlink to the next and having to pick one line for poetry.

In the years before the z-trip our travelling was mainly for business. I mainly saw airports, train stations, motorways, and corporate headquarters. Though it should not have been a secret, the z-trip showed us that we live in a country comprised of fields and forests, of land not completely sealed by the tokens of 20th century’s civilization.

z-trip, as in the bucolic cliché

z-trip, magic well

z-trip, wind farm

We had to neglect some z-villages in the Western, Alpine regions to keep kilometers to a reasonable level. Nevertheless, we saw enough small villages that made us wonder how people can cope with tons of snow.

It was like in these movies portraying New Yorkers travelling to the wilderness of Alaska for the first time, having to deal with harsh weather and raccoons. I realized how clichéd, biased, and distorted some of my views were (… and yet, I use more clichés now to make my point!).

z-trip, wild animals

We both quit our corporate jobs the day after we had returned from that trip.

z-trip, settlers' selfie

Travelling like this was like using the internet in the pre-social-media era: Jumping from one obscure private website – designed by Microsoft FrontPage, with pink marquee taglines – to the next, not sharing and commenting on it.

I crafted my first website in 1997 – with FrontPage, I admit, and for business – but I was very reluctant to enter the interactive social web for a long time. My reluctance was the topic of my very first WordPress post. Since three years I have been exploring Web 2.0, and I am now returning to the z-travelling style of using the internet.

Update on Edible ‘Weed’

After two physics articles with too much links I owe you an image-only link-free post. This is an update to my catalogue of edible wildflowers in our lawn meadow.

I amended the original list with one amazing wild vegetable: Meadow Goatsbeard. In past years I tried to eradicate it, now I don’t scythe certain patches but carefully use grass shears, avoiding to cut its signature yellow bloom:

meadow-goatsbeard

It can be used as fake spinach and for salad – I vouch for both! Insiders say the roots are the real delicacy (tasting like salsifies), but this year I will not yet dig out the roots but rather let them flower and disperse their seeds. The most amazing feature is that it grows and grows new leaves, despite it had not rained in the past week and maximum temperatures were up to 30°C.

Here is the result of a single ‘harvesting session’ (left):

… side-by-side with a Yarrow leaves (right). We are self-sufficient on tea since April. thanks yarrow and Lemon Balm.

In the background of the first image: the tomato plants attached to the solar collector. So far they look good this year, blooming nicely:

tomatoes-collector-june-2015

We weren’t able to discard ‘spare’ tomato seedlings – so they grow near the compost pile. Clients visiting us to see the heat pump system may think we are in the tomato business (one strawberry plant in the middle):

even-more-tomatoesFinally my secret favorite has started growing – Portulaca / Purslane. Yes, I think it tastes like pepper!

The wild, creeping variety (… and even more ‘spare’ tomatoes in the background):

The plants in the background is for decoration and suppression of other weed, such as grass 🙂 Some variety of Sedum Reflexum (yellowish), and Phlox.

Speaking about Sedum: White Stonecrop was a main ingredient in the typical spring salad, together with Dandelions, and the absolutely amazingly tasty Fireweed.

Now White Stonecrop is nearly blooming (in the image below: in front of seed pods of Pasque Flowers / Prairie Crocus[*] Afterwards it will wither – then harvesting season is over.

[*] I am sure I picked the most uncommon common name often in this post, actually I am not even sure about German ones.

Fireweed – despite the temptation I keep a few for seeds:

Poppy’s seed capsules have some aesthetic value, but they cannot beat Nigella Sativa. Here is spice in the making – alien space probes inspecting the garden.

nigella-seed-capsules

Those plants we finally picked for cultivating – weed or not – are also the ones that turned out maintenance-free, drought-resistant, and capable of taking care of themselves – suppressing other unwanted plants. The remaining ‘work’ – if you want to call it like that – is truly enjoyable and like the proverbial raking the Zen garden.

We have never used weed killers nor fertilizer except the soil from compost. We only water tomato plants and mediterranean herbs a bit, so scything is due only once every two or three weeks. I don’t care if the meadow is burnt down to straw in summer.

These are my favorite drought-tolerant alien periscopes –  Hen and Chicks, used as a medicinal herb, otherwise too bitter even for me.

alien-hen-and-chicks

We don’t fight pests, and I live in fear what will happen to eggplants’ fruits. I have learned that those are (in our climate) slugs’ favorite diet in summer. In this case the, last resort is my office gardening experiments. To  my surprise, this spare plant has some flower buds already.

Social Debt (Tech Professional’s Anecdotes)

I have enjoyed Ben Horowitz’ book The Hard Thing About Hard Things. Farnamstreet’s review is perfect so I will not attempt at writing one. I will focus on one idea I found most intriguing.

I read Horowitz’ book as an account of dealing with hard decisions in general, about having to decide alone, about personal accountability, about having to pick the lesser of two evils.

The idea that stuck with me in particular is Management Debt, and Horowitz also blogged about this.

… management debt is incurred when you make an expedient, short-term management decision with an expensive, long-term consequence.

You accumulate Management Debt if you try to fix an organizational issue quickly by acting inconsistently. Horowitz’ example: You might give an employee a raise in order to stop her from leaving the company. But she had discussed her plans with another employee who then wonders why she stayed; so she feels pressed to explain the reason to him. Then others learn how to blackmail you in order to get a raise, etc..

From my short stint as a manager I am familiar with such situations but I rather like to extend the concept to Social or Political Debt. I believe that we, as human social animals, tend to focus on resolving the conflict right in front of you, rather than considering seemingly abstract consequences in the future.

I am thinking of the expert bombarded with all kinds of requests. As a professional it is hard to avoid them: People who to want to pick your brain and just like to have 5 minutes so you can glance over their problems. For free. Trying to help all of them – on top of working with paying clients – would be the equivalent of trying to copy a full book at the photocopier but yielding to anybody who wants to copy just a single page.

As a fallible human you might give in to the most intrusive requester just to get rid of him or her. You think that explaining your seemingly cold-hearted rationale would take more time and would be more emotionally taxing than just fulfilling the request.

But those people will return with more problems, and their acquaintances will, too. You have incurred debt, and there is interest rate. The moment of refusal might be difficult though, in particular with requests in the blurry area between business and private. How to say No to that alleged or self-declared old friend?

I am a believer in 1) Stating clearly what you don’t want and don’t do (rather than focusing on the positive) without feeling the need to explain yourself and 2) “Principles” – a short list of your values, or guiding principles you always follow. Both need need to be ingrained in your mind so that you react accordingly in case you receive those e-mails and calls out of the blue.

The paradoxical or sad thing is that explanations are most often futile. There are many good reasons – both ethical and business-wise – for not jumping onto such requests. The obvious one being limited time and treating all clients equal, but the best one in my point of view being the value of true expertise: Based on years of experience you might only need five minutes to solve a problem that requires somebody else doing days of research. That’s exactly why those first minutes might be the most valuable.

I am speaking from experience although such things fortunately did happen to me rarely. But when they did, it was freaking me out. I once got a call from an unknown lawyer who was in the middle of installing his very own Public Key Infrastructure; he started asking technical questions before introducing himself. I tried to explain that I was actually charging people for such services, and that I assumed he did not do legal counselling for free either. His response was that he was maintaining all his IT stuff by himself – just this topic was too complicated for him so he needed advice. So services should be free if a professional solves a particularly tricky problem. This defies common sense.

I also thought I had a killer argument, non-refutable. I am actually providing technical information on ‘the internet’ – the same sort of answers or materials I would charge clients for. The difference is that I am not obligated to do this, so I pick this case by case. I believe in open-source-style sharing in a community of like-minded members. I am a believer in demonstrating skills in real time instead of showing off certificates – it goes without saying this might include giving away some valuable advice for demo purposes at the start of a business relationship.

Unfortunately, this demo-for-business argument that is used too often by people who want to milk your know-how forever – just testing how far they can go – without ever really considering a ‘business relationship’. As soon as you tell them the answer to the next question will not be free of charge anymore, they suddenly stop asking.

Fortunately, I get enough feedback by providing so much detailed information for free!!. A few people who don’t get it would not shatter my confidence. Interestingly, people who still challenge me (But then you don’t have time for me??) are those whom I would not consider part of any ‘sharing’ communities or get their spirit in the slightest. I think all those issues belong in the category: Either you get it immediately and communication is based on tacit understanding what is normal and appropriate – or all explanations are in vain.

Many years ago I had been asked literally if I would like to work for free. Corporations send out request for proposals and ask for lots of free concepts and presentations – until they have gathered enough know-how from all the potential vendors invited so that finally they have learned enough from the ‘pitches’ and can do the whole project on their own. Finally I had my antennas finely tuned to all your typical manipulations methods (I have already told X you will do [unpaid honorable engagement] Y – if you don’t, this will get me into serious troubles!). Many people are driven by short-term impulses, not by malice (I have to solve this problem or my boss will kill me!) and they respond to logical arguments: What would you say if you were a paying client and find out that I do free consulting for other people at random? Some manipulators are hopeless cases though, especially if they think they provide something in return that is actually less than useless to you.

Horowitz’ war stories resonated with me more than I expected. He emphasizes dealing with organizationally or psychologically difficult issues head-on. I read his advice as: Better act sooner than later, better state the ugly truth upfront. Better take some decision at all, even if it is just 55% versus 45%. Communicate clearly, don’t use fluffy phrases. Sometimes people explicitly appreciated my way of saying No immediately and unambiguously, instead of endless dithering and not trying to hurt anybody which seems to have become fashionable in times of Networking and You Will Always Meet Two Times.

wine-clarity

Searching my own images for own that would represent both mental clarity as well as difficult decisions – I zoomed in this one immediately. (Vineyards close to my home village, evening at the beginning of May.)

Although this is tagged with ‘rant’ it should not be interpreted as what I actually consider pointless and energy-draining – endless rants about common practices in your industry sector that you cannot change but have to live with. I am in the Love It, Change It, Or Leave It camp. I have also been writing about the past, and often a single annoying event of that sort had made me shift gears.

I believe the best – and most productive – way to cope with weird requests is to either: Respond clearly and immediately using a standardized I-don’t-do reply, then ignore them as an accidental, misguided question that just happened to end up in your inbox; or: to analyze if an aspect of your previous communication might have invited such inquiries, and improve your future communications. And don’t aim at being liked by anybody, anytime.
